T-300 is a carbon fiber from Toray. 934 is an epoxy formulation from Hexcel or Solvay (depending on if it is for space or other application. This is due to businesses that were bought/sold back in the 90's and the government anti-trust rulings).

There are fiber properties, resin properties and composite properties. Fiber properties are almost always determined by testing composite laminates and calculating the fiber contribution. You can only buy 934 from Solvay or Hexcel, and they have lots of data on that product.

Yes, properties are very different between bare fiber and prepreg ( cured into a composite). If you don’t know anything about composites, please go hire someone who does.

Thank you Compositepro and SWComposites!

Thanks for your reminder @ewh

Why not check for yourself?

NCAMP & AGATE have properties databases (not sure about this specific combination though).

@WindWright, thanks for the AGATE link. I did check up AGATE data and milspec...

Is NCAMP behind a pay wall now??

There they are!
